Just remove the call to decode: 
      $worksheet->write($rowCount, $colCount, $Field, $gFmtBold);

[download]

I also had to remove the following lines from the script to test it (they're irrelevant to the question, anyway): 

use Locale::Msgcat;
use Number::Localization;
use Presentation;

[download]

And I had to prepend 

use Excel::Writer::XLSX;

[download]

See Short, Self Contained, Correct Example on how to help us to help you.

See the module's documentation on the details:

If the data is in UTF-8 format then Excel::Writer::XLSX will handle it automatically.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
